Linux Journal builds a low power NAS with an Arm-based server and USB hard drives.

As an experiment, and finally to get rid of that large, inefficient and ugly tower case, I decided to use the new Trim-Slice as the base for an ultra-low-power, ultra-small replacement file server. The Trim-Slice is built on the NVIDIA Tegra 2 platform, and the specific model I purchased features a 1GHz dual-core ARM Cortex A9 processor, 1GB of RAM and a 32GB SATA SSD.

We have been playing around with the QNAP TS-659 Pro II unit over the last month or so. Based on the Intel Atom D525 platform, it has 6 bays and dual GbE ports, making it a candidate for the high end SMB market.

Synology has a sensible model number nomenclature in which the last two digits refer to the year through which the model is intended for sale. The first set of digits refer to the maximum number of bays supported. Some models have a + at the end, signifying higher performance. Today, we have the DS211+ for review. The DS refers to the product category, Disk Station. 2 indicates a 2 bay model, and the 11 indicates a 2011 model. It is supposed to have a higher performance compared to the DS211 which was released in November 2010.
